' ,2 Claims; (01. rol -330.): r

' f of; t e bolt H the hubs e" and m are ivo au invention relates to an'autom'atic can marking machine.

Canners are now requested to mark contents,

indeliblyon eachtin can of food stuff consigned to our over-sea fighting forces assuring positive product identification should labels bed'estroyed or washed 01f.) f

Therefore; an object of this invention is the production of a sturdy machine designed for quick,'easy installation on. vegetab1e,firuit, or juice fillers, on No. hand pack lines or at any place in the linewherecontainers are 'mjovingv ers, cans or the like, which can be easily at-.

tached" to and cooperate withgthe can filling machine, or any other canning or packaging equipment. I s v l Wi'thi the foregoing and other objects. in view my invention comprises certain novel construetions, combinations, and arrangements" offlparts as will be hereinafter fully described,. illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the'drawings:

Figure 1 is a view in side elevation of a machine constructed in accordance with the present invention, while Figure 2 is a top plan view of the same.

Figure 3 is an enlarged fragmentary view of the machine, showing particularly the printing and inking rollers.

Referring to the drawings, in which thepreferred embodiment of this invention is illustrated, I designates in general the casting or frame of a filling machine. Thev bracket 2 is provided with an integral extension 3; the ex" tension 3 has a solid web 4 and at its outer end is a hub 5 (Fig. 1)-. A straight auxiliary arm 6 has its inner end against the bottom of hub 5 (Fig. 1) and by means of a bolt and nut I the arm 6 is adjustably secured in a fixed position upon the bracketrZ. A swinging primary arm is provided at its innerendwith a hub '9. 1

Hub 9 engages the hub II), which hub, in is formed on the outer end of auxiliary arm 6. By means A bfolt I6 is mounted upon the innercurved connectedtogethen 1 An upstanding boss II is formed on the auxil'ia'ry armjidntermediateits ends; and on boss 12 isiposition'ed adjustable stop plate l3". By

means of the b'olta'n'd nut structure [4 the plate [3,? "is held' in the desiredadjusted position. Mountedlupon/one side of said plate I3" is a rubber bumpe'r'l'5. The primary arm Bis'adapted to bear against rubber bumper l5.

portion off arm 8' and a bolt l'l is mounted upon the web 4'. A coilspring' IBhas one end mountedon bolt l6 andits other end is" mounted upon bolt 11, whereby a normal pull is exerted upon prifnary arm' 8ffor' holding; the printing roller- Thejprinting'ro'llerfll'9 rotatably mounted on bolt 21 which" bolt isic'arried on the'outer end of primary arm The printing roller comprises 'a body 22ithat"has traction bands" 23 partly seated therein, (Fig. 3) and at" its c'enter is -a type unit-. 24. This type" unit can be of any desired structure,'carrying the means of designation; to'be printed dir'ectl'yon the can or container for positivel'y indicating the contents of: the can. "This printing roller freely rotates upon the. arm 8 with the passing cans causing the roller to. rotate by reason of the frictional contact. P "1 A rotary post. 25 is mounted upon the primary arm" 8 with a nut 26 on's'aid post and engaging the arm v8. An arm 21 is fixedly 'mounted by lock screw 28 upon post 25. The outer end of arm 21 surrounds hollowtube 29,

and tube 29 is kept from rotating within the 3 r fixed arm by means of a set screw 30. The

pass therethrough. On tube 29 is a rotatable sleeve 32 that has apertures -or openings perhollow tube 'zsisnprovided with a plurality of,

apertures 3| (Fig. 3), which permit the-ink to mitting ink to pass-from apertures 3| through the sleeve and onto the felt washers 3 3, whereby,

the inking roller is supplied with ink for inking the type unit 24. A collar 34 is fixedly secured by set screw 35 on the lowerend of hollow tube 29, holding the inking roller in position. The outer end or hub-end of the arm 2'! acts as the holding means at the top of tube 25 preventing upward sliding movement of the inking roller on tube 29. An eye35 is formed on the lower end of tube 29, and one end of coil spring 36 is fastened to said eye; the other end of said coil spring is fastened at 31 to the swinging arm 8.

l flanges. (Fig. l) and a slot 4|.

This spring 35 holds the inking roller in contact with the type unit 24. 1 A cover 38 is placed on bolt 2| above the print-j ing roller 24 and by means of nut 39 the cover is held in place.

The slotted portion 4| of cover 38 partly surrounds the ho-l-j low tube 29. 1 p

.A pipe unit 42 is employed, including an elbow 43, valv 44, and an elbow 45. Theelbow 4s is,1

screwed upon the upper threaded end of "hollow; tube 29 and the extension 46 of reservoir .41 is threaded into elbow 45.

Thereservoir 41 is of 'a general hopper-like? structure and has a closed portion 48 (Fig. 2) :16 at its top. A stud 49 extends upwardly from thef closed portion 48. I A removable cap 50 is placedon the top of reservoir 41, normally entirely clos-l ing the same. An angle clamp is placed against cap 50, anda holding bolt 52 extends through the "20 outer end of angle clamp '5landis threaded into stud 49. When bolt.52 is screwedfdown tight upon clainpil the cap 50 will be securely held:

upon the reservoir, tightlyclosing the same.

The arm 21,,type unit 42 and reservoir 41 are looked upon the posts -25 against independent movement, whereby when post25is vrotated,'the reservoir andthe'inking roller will bodily move togetherQ I If for any reason the primary arm I8 is swung, so

outwardly uponits pivot, constituted'by bolt l I, and is permitted to rebound in the direction of the'cans it will strike the bumper l5 and take. -up the sudden shock, the tendency of the inward movement of thearm'being caused by the 36 relatively powerful spring 18. Under normal operating conditions the spring I8 is sufliciently;

strong to hold the printing roller in contact with the passing cans. The spring 36 is strong enough i to normally hold the inking roller'in contact with 40 the printing roller for efficient results. 7

By loosening the nut on bolt l4 the stop or bumper plate 13 can beaccuratelyadjusted to take up all shock and then the operator can tighten the nut, sufficiently to hold the stop plate: in thedesir'ed adjusted position.

'By means of the valve 44 the supply of ink from reservoir 41 to the inking roller can be nicely adjusted. The cover 38 partly shields the operator against comingin-contact with the inking and printing rollers. i

While I have described the preferredembodi- This cover has two depending 5 ment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In 'a. machine of: the. class described, the

combination of a bracket,"anauxiliary arm ,adjustably land fixedly secured to said bracket, said auxiliary arm provided with an upstanding boss,

a horizontal stop plate adjustably mounted on' combinationof a'bracketprovided with an 'extension and asolid web, said extension provided at' its outer end with a hub, anauxiliary straight arm having its inner end engaging the bottom of said hub, means securing said auxiliary arm and said hub together, said auxiliary arm provided I, at its outer end with a hub, a primary swinging arm provided atits inner end with a hub, said lastmentioned hub engaging the hub on the out- I er, end of said auxiliary arm, said auxiliary armprovided intermediate its ends with a bumper device, said swinging, arm being, curved near its inner end and said curved portion normally en gaging said bumper device, a coil spring and means connecting one end to the curved portion of the swinging arm and the other end to a portion oi the web of the bracket, a printing roller and means pivotally mounting saidprinting roller on the outer end of said swinging arm, a rotary post, extending at its lower end into sa d swingin arm, a fixed arm on saidrotarypost, said fixed arm having a hub-like portion omits outer end, and inking-roller normally, against said printing roller, said inking roller havinga hollow tube extending through said hub-like portion, a reservoir, and valved means bodily sup-.

porting said reservoir upon the upper or outer end of said hollow tube. 1
